NIH Releases Mpox Research Agenda
September 17, 2024
The NIAID mpox research agenda focuses on four key objectives: increasing knowledge about the biology of all clades—also known as strains—of the virus that causes mpox, including how the virus is transmitted and how people’s immune systems respond to it; evaluating dosing regimens of current vaccines to stretch the vaccine supply and developing novel vaccine concepts; advancing existing and novel treatments, including antivirals and monoclonal antibodies; and supporting strategies for detecting the virus to facilitate clinical care and epidemiological surveillance.
NIH Awards Establish Pandemic Preparedness Research Network
September 13, 2024
The Research and Development of Vaccines and Monoclonal Antibodies for Pandemic Preparedness network—called ReVAMPP—will focus its research efforts on “prototype pathogens,” representative pathogens from virus families known to infect humans, and high-priority pathogens that have the potential to cause deadly diseases. The pandemic preparedness research network will conduct research on high-priority pathogens most likely to threaten human health with the goal of developing effective vaccines and monoclonal antibodies.
NIH Awards Will Support Innovation in Syphilis Diagnostics
September 3, 2024
NIAID has awarded grants for 10 projects to improve diagnostic tools for congenital and adult syphilis—conditions currently diagnosed with a sequence of tests, each with limited precision. The Centers for Disease Control and Prevention estimates that adult and congenital syphilis cases increased by 80% and 183% respectively between 2018 and 2022—a crisis that prompted the U.S. Department of Health and Human Services (HHS) to establish a national taskforce to respond to the epidemic.

Novel Vaccine Concept Generates Immune Responses that Could Produce Multiple Types of HIV Broadly Neutralizing Antibodies
May 30, 2024
Using a combination of cutting-edge immunologic technologies, researchers have successfully stimulated animals’ immune systems to induce rare precursor B cells of a class of HIV broadly neutralizing antibodies (bNAbs). The findings, published today in Nature Immunology, are an encouraging, incremental step in developing a preventive HIV vaccine.
Lower Dose of Mpox Vaccine Is Safe and Generates Six-Week Antibody Response Equivalent to Standard Regimen
April 27, 2024
A dose-sparing intradermal mpox vaccination regimen was safe and generated an antibody response equivalent to that induced by the standard regimen at six weeks (two weeks after the second dose), according to findings presented today at the European Society of Clinical Microbiology and Infectious Diseases Global Congress in Barcelona. The results suggest that antibody responses contributed to the effectiveness of dose-sparing mpox vaccine regimens used during the 2022 U.S. outbreak.
World TB Day 2024 – Yes! We Can End TB!
March 22, 2024
In observance of World Tuberculosis Day (Sunday, March 24), NIAID joins our partners in reaffirming our commitment to ending the tuberculosis (TB) pandemic while honoring the lives lost to TB disease.
NIH Scientists Find Weak Points on Epstein-Barr Virus
March 12, 2024
Studies of interactions between two lab-generated monoclonal antibodies (mAbs) and an essential Epstein-Barr virus (EBV) protein have uncovered targets that could be exploited in designing treatments and vaccines for this extremely common virus. The research was led by Jeffrey I. Cohen, M.D., and colleagues from NIAID.
New Antibodies Target “Dark Side” of Influenza Virus Protein
March 1, 2024
Researchers at the National Institutes of Health have identified antibodies targeting a hard-to-spot region of the influenza virus, shedding light on the relatively unexplored “dark side” of the neuraminidase (NA) protein head.
COVID-19 Vaccination and Boosting During Pregnancy Protects Infants for Six Months
February 14, 2024
Women who receive an mRNA-based COVID-19 vaccination or booster during pregnancy can provide their infants with strong protection against symptomatic COVID-19 infection for at least six months after birth. These findings reinforce the importance of receiving both a COVID-19 vaccine and booster during pregnancy to ensure that infants are born with robust protection that lasts until they are old enough to be vaccinated.
Researchers Create Safer Form of Coxiella burnetii for Scientific Use
January 25, 2024
Scientists have unexpectedly discovered that the weakened form of the bacteria Coxiella burnetii (C. burnetii) not typically known to cause disease, naturally acquired an ability to do so. C. burnetii causes Q Fever in humans and its weakened forms are those used for scientific purposes. Subsequently, the scientists identified the genetic mutation responsible for the increased ability to cause disease (virulence) and created a form of the bacteria without the genetic flaw that could safely be used for research.
NIH-Developed HIV Antibodies Protect Animals in Proof-of-Concept Study
January 17, 2024
Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The study, published in Science Translational Medicine, was led by the Vaccine Research Center (VRC) at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
NIH Research Identifies Opportunities to Improve Future HIV Vaccine Candidates
December 14, 2023
